The distance control ECU detects washer operation. Cruise control will be canceled by the distance control ECU if the windshield wipers operate in HI or LO mode.

The distance control switch sets the vehicle-to-vehicle distance control mode. The distance control switch is installed in the steering pad switch. The vehicle-to-vehicle distance set value can be changed by operating the steering pad switch (distance control switch) while the dynamic radar cruise control system is in operation. The steering pad switch uses the CAN communication line to communicate with each ECU.

This circuit provides power to the millimeter wave radar sensor. The millimeter wave radar sensor emits radio waves towards an object in front and measures the distance and direction of the object by receiving the wave reflections. Based on the reflections, the sensor calculates the difference in speed between the vehicle and the object in front. This data is transmitted to the distance control ECU.
